A shrinkage-thresholding Metropolis adjusted Langevin algorithm for Bayesian variable selection
Amandine Schreck, Gersende Fort, Sylvain Le Corff +1
This paper introduces a new Markov Chain Monte Carlo method for Bayesian variable selection in high dimensional settings. The algorithm is a Hastings-Metropolis sampler with a prop…
Planck intermediate results. XVII. Emission of dust in the diffuse interstellar medium from the far-infrared to microwave frequencies
Planck Collaboration, A. Abergel, P. A. R. Ade +196
The dust-HI correlation is used to characterize the emission properties of dust in the diffuse interstellar medium. We cross-correlate sky maps from Planck, WMAP, and DIRBE, at 17…
Blind Denoising with Random Greedy Pursuits
Manuel Moussallam, Alexandre Gramfort, Laurent Daudet +1
Denoising methods require some assumptions about the signal of interest and the noise. While most denoising procedures require some knowledge about the noise level, which may be un…
An SIR Graph Growth Model for the Epidemics of Communicable Diseases
Charanpal Dhanjal, Stéphan Clémençon
It is the main purpose of this paper to introduce a graph-valued stochastic process in order to model the spread of a communicable infectious disease. The major novelty of the SIR…
Simplicial Homology for Future Cellular Networks
Anaïs Vergne, Laurent Decreusefond, Philippe Martins
Simplicial homology is a tool that provides a mathematical way to compute the connectivity and the coverage of a cellular network without any node location information. In this art…
Random Abstract Simplicial Complexes Reduction
Anaïs Vergne, Laurent Decreusefond, Philippe Martins
Random abstract simplicial complex representation provides a mathematical description of wireless networks and their topology. In order to reduce the energy consumption in this typ…
Planck 2013 results. XI. All-sky model of thermal dust emission
Planck Collaboration, A. Abergel, P. A. R. Ade +244
This paper presents an all-sky model of dust emission from the Planck 857, 545 and 353 GHz, and IRAS 100 micron data. Using a modified black-body fit to the data we present all-sky…
Learning Reputation in an Authorship Network
Charanpal Dhanjal, Stéphan Clémençon
The problem of searching for experts in a given academic field is hugely important in both industry and academia. We study exactly this issue with respect to a database of authors…
Entanglement, Flow and Classical Simulatability in Measurement Based Quantum Computation
Damian Markham, Elham Kashefi
The question of which and how a particular class of entangled resource states (known as graph states) can be used for measurement based quantum computation (MBQC) recently gave ris…
Perfect Simulation of Determinantal Point Processes
Laurent Decreusefond, Ian Flint, Kah Choon Low
Determinantal point processes (DPP) serve as a practicable modeling for many applications of repulsive point processes. A known approach for simulation was proposed in \cite{Hough(…
Time series prediction via aggregation : an oracle bound including numerical cost
Andres Sanchez-Perez
We address the problem of forecasting a time series meeting the Causal Bernoulli Shift model, using a parametric set of predictors. The aggregation technique provides a predictor w…
General inner approximation of vector-valued functions
Mullier Olivier, Éric Goubault, Michel Kieffer +1
This paper addresses the problem of evaluating a subset of the range of a vector-valued function. It is based on a work by Gold- sztejn and Jaulin which provides methods based on i…
Analysis of the limiting spectral measure of large random matrices of the separable covariance type
Romain Couillet, Walid Hachem
Consider the random matrix where and are deterministic Hermitian nonnegative matrices with respective dimensions a…
Efficiency of the Wang-Landau algorithm: a simple test case
G. Fort, B. Jourdain, E. Kuhn +2
We analyze the efficiency of the Wang-Landau algorithm to sample a multimodal distribution on a prototypical simple test case. We show that the exit time from a metastable state is…
Second order scattering descriptors predict fMRI activity due to visual textures
Michael Eickenberg, Fabian Pedregosa, Senoussi Mehdi +2
Second layer scattering descriptors are known to provide good classification performance on natural quasi-stationary processes such as visual textures due to their sensitivity to h…
Improving tag recommendation by folding in more consistency
Modou Gueye, Talel Abdessalem, Hubert Naacke
Tag recommendation is a major aspect of collaborative tagging systems. It aims to recommend tags to a user for tagging an item. In this paper we present a part of our work in progr…
Smooth minimization of nonsmooth functions with parallel coordinate descent methods
Olivier Fercoq, Peter Richtárik
We study the performance of a family of randomized parallel coordinate descent methods for minimizing the sum of a nonsmooth and separable convex functions. The problem class inclu…
Central Limit Theorems for Stochastic Approximation with controlled Markov chain dynamics
Gersende Fort
This paper provides a Central Limit Theorem (CLT) for a process satisfying a stochastic approximation (SA) equation of the form $θ_{n+1} = θ_n + γ_{n+1} H(θ_n,X_…
Planck 2013 results. XXX. Cosmic infrared background measurements and implications for star formation
Planck Collaboration, P. A. R. Ade, N. Aghanim +238
We present new measurements of CIB anisotropies using Planck. Combining HFI data with IRAS, the angular auto- and cross frequency power spectrum is measured from 143 to 3000 GHz, a…
Gaussian fluctuations for linear spectral statistics of large random covariance matrices
Jamal Najim, Jianfeng Yao
Consider a matrix , where is a nonnegative definite Hermitian matrix and is a random matrix with i.i.d. real or complex…
Adiabatic graph-state quantum computation
Bobby Antonio, Damian Markham, Janet Anders
Measurement-based quantum computation (MBQC) and holonomic quantum computation (HQC) are two very different computational methods. The computation in MBQC is driven by adaptive mea…
Planck intermediate results. XV. A study of anomalous microwave emission in Galactic clouds
Planck Collaboration, P. A. R. Ade, N. Aghanim +180
Anomalous microwave emission (AME) is believed to be due to electric dipole radiation from small spinning dust grains. The aim of this paper is a statistical study of the basic pro…
